BBS02 conversion on a Giant MTB

[Son Nguyen]

Just finished my BBS02 conversion. It was the first time i have done it. I bought the bike brand new so i asked the shop to remove the crank for me. When i got home, it took me about an hour to put everything together. It was very easy. I got the kit from EM3EV. i rode the bike and instantly fell in love. Here are some pics.

what bbos 2 model did u purchase? 350,500 or 750 and what battery did you choose?

I got the 48V 500w kit with the 8.2ah battery . Im only 145lbs so it is plenty powerful for me. I also have the same kit for my wife on order.

Congratulations, nice job. Have a ball, if you like the bike now, it will only get better. When you and your wife have ebikes you'll spend a lot of time riding together.......

Hi,

I haven't really looked at the HD specs. and to my knowledge the drives won't be available for at least another 1 or 2 months. I believe most of the discussion about the drive are from reviewers who have gotten early models to demo. Have you found any outlets that are actually taking orders with pricing??

you can pre-order it from letric-cycles. base price for the eRAD model is 1299 but jumps up quickly. while lunacycles has it for 799$ or with a 52v 13.5 ah battery for 1199.95$.

Not a bad price.....but I did notice that the BB size offered for a fat bike is 100MM which is the standard and probably will work with the bike you chose. The only thing that gives me pause is the 102.5 MM spec. on the bike you linked.

Just to satisfy my curiosity I wanted to check some more Gravity FB's on BD and I found some with a BB spec. VP CARTRIDGE 100MM/144MM

This is what I would have expected....which makes me wonder what the odd 102.5MM spec is all about? Maybe nothing, but ??????

Yeah, I'm just going to order the one you linked. It looks good, has a good review on youtube and 100$ cheaper. If I need a FF suspension I can upgrade that later, but I'll probably just get a body float or thudbuster first. thx

That bike is awesome! I would be stoked with that bike!
What size BB fit the Giant MTB. Do you know if they will all be the same on every Giant MTB? Do you just remove the left trigger shifter?

It was a 68mm BB. perfect fit for the bbs02. I don't know much about the other giant bikes but I'm sure it will fit since 68-73mm BB are pretty standard. Yea i removed the left trigger shifter since it was for the front derailure and wasn't needed. Here are pictures of my wife's bike I recently built.

WOW! IMO you guys have some bad azz bikes! What model was that MTB from Giant you used?
